=========================================================== Ubuntu Security Notice USN-305-1 June 27, 2006 openldap2, openldap2.2 vulnerability CVE-2006-2754 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 5.04 Ubuntu 5.10 Ubuntu 6.06 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 5.04: slapd 2.1.30-3ubuntu3.2 Ubuntu 5.10: slapd 2.2.26-3ubuntu0.1 Ubuntu 6.06 LTS: slapd 2.2.26-5ubuntu2.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: When processing overly long host names in OpenLDAP's slurpd replication server, a buffer overflow caused slurpd to crash. If an attacker manages to inject a specially crafted host name into slurpd, this might also be exploited to execute arbitrary code with slurpd's privileges; however, since slurpd is usually set up to replicate only trusted machines, this should not be exploitable in normal cases.
